Abstract

A surgical instrument comprising an end effector, a firing member, a motor, and a control circuit is disclosed. The end effector comprises a first jaw, a second jaw movable relative to the first jaw to grasp tissue therebetween, a staple cartridge comprising staples, a first sensor at a first position of the end effector, and a second sensor at a second position of the end effector. The firing member is movable in a firing motion to deploy the staples. The motor is configured to cause the firing motion. The control circuit is configured to receive a first output of the first sensor, receive a second output of the second sensor, and cause the motor to adjust the firing motion based on the first and second outputs. The first output is indicative of a tissue property and the second output is indicative of the tissue property.

Dependent claims

A surgical instrument, comprising:

an end effector, comprising:
a first jaw;
a second jaw movable relative to the first jaw to grasp tissue therebetween;
a staple cartridge comprising staples;
a first sensor at a first position along a length of the end effector, wherein the first sensor is configured to measure a parameter indicative of a property of the tissue at the first position;
and
a second sensor spaced apart from the first sensor, wherein the second sensor is at a second position along the length of the end effector, wherein the first position is proximal to the second position, and wherein the second sensor is configured to measure the parameter indicative of the property of the tissue at the second position;
a firing member movable in a firing motion to deploy the staples into the tissue;
a motor operably coupled to the firing member, wherein the motor is configured to cause the firing motion;
and
a control circuit configured to cause the motor to adjust the firing motion based on measured values of the parameter at the first position and at the second position.
